Protective equipment, including personal protective equipment (PPE) for eyes, face, head, and extremities, protective clothing, protective shields and barriers, shall be provided, used, and maintained in a sanitary and reliable condition wherever it is necessary by reason of hazards of processes or environment, chemical hazards, or mechanical irritants encountered in a manner capable of causing injury or impairment in the function of any part of the body through absorption, inhalation or physical contact. Moore County Schools shall provide training to each employee who is required by this section to use PPE. Each such employee shall be trained to know at least the following: a. b. c. d. e. 3.1 When PPE is necessary What PPE is necessary How to properly don, doff, adjust, wear and sanitize PPE The limitations of the PPE The proper care, maintenance, useful life and disposal of the PPE Eye Protection 3.1.1 All eye protection must meet ANSI Z87.1 Standard 3.1.2 Eye and face protection devices shall protect against the intended hazard and be marked to identify the manufacturer, reasonably comfortable and proper fit, durable, capable of being disinfected, easy to clean and in good repair. 3.1.3 The teacher shall ensure that each affected student shall use appropriate eye and face protection when exposed to eye or face hazards from flying particles, molten metal, liquid chemicals, acids or caustic liquids, chemicals gases or vapors or potentially injurious light radiation. 3.1.4 Teachers shall ensure that each affected student shall use eye protection that provides side protection when there is a hazard from flying objects. Detachable side protectors (e.g., clip-on or slide-on side shields) must be in place. 3.1.5 The teacher shall ensure that each student who wears prescription lenses while engaged in operations that involve eye hazards shall wear eye protection that can Moore County Schools Chemical Hygiene Plan -4- be worn over the prescription lenses without disturbing the proper position of the prescription lenses or the protective lenses. 3.1.6 Goggles should seal around the eyes to prevent entrance of aerosols or splashed liquids. 3.1.7 Goggles, for most school science settings, should be of the "splash" type. They should seal comfortably to the face. Ventilated frames, or specially coated lenses, are generally required to prevent fogging. Scratched faceplates compromise goggle integrity and should be disposed. Goggles with deep scratches should be eliminated immediately, as integrity may have been compromised. 3.1.8 North Carolina OSHA recommends that goggles be thoroughly cleansed with soap and warm water, alcohol, or UV radiation. 3.1.9 Visitors to laboratories shall be furnished with and required to wear eye safety devices while experiments are in progress. 3.1.10 Face shields are for teachers’ use only. Face shields should be viewed as supplementary protection to goggles for a larger area of the face. They are not replacements for goggles. No experiments shall be performed in the lab that requires use of more than indirect vented chemical splash goggles for students. 3.1.11 It is recommended that contact lenses not be used in laboratories unless the student has an eye condition that requires their use. If it is absolutely necessary to wear contacts, the person should wear indirect or non-vented chemical splash goggles. 3.2 Hand Protection 3.2.1 Appropriate hand protection shall be used “when employees’ hands are exposed to hazards such as those from skin absorption of harmful substances; severe cuts or lacerations; severe abrasions; punctures; chemical burns; thermal burns; and harmful temperature extremes.” OSHA 29 CFR 1910.138. Hand protection shall be based on the chemical compatibility charts supplied by the glove manufacturers. These charts typically provide the performance characteristics in response to particular chemicals with regards to material degradation rating, breakthrough time and permeation rate. There are six basic types of gloves including: a. Neoprene - for sunlight, heat, organic solvents b. Aluminized - for hot or cold materials c. Leather - for glass, bites, sharp objects, heat, cold d. Polyethylene - often disposable for solvents, acids, detergents e. Plastic or latex - for general non-hazardous chemicals (Non-latex gloves shall be available for those with allergies) f. Nitrile - for acids and organic solvents. Moore County Schools Chemical Hygiene Plan -5- 3.2.2 Gloves shall be worn that offer protection for all hazards found in the lab. Gloves shall be inspected before wearing to check for tears and punctures. 3.3 Clothing Requirements 3.3.1 Students shall wear appropriate clothing as designated by the Moore County Schools’ Dress Code. Open-toed shoes should not be worn in the lab. 3.3.2 Neck- ties should be removed when in the lab area. Loose jewelry is prohibited in the lab area.

Watch straps that are made of absorbent material should be removed. 3.3.3 A chemical- resistant apron is required when working with hot liquids, corrosive chemicals, or when there is a chemical spill or splash hazard present. Aprons should protect the body torso down to the knees. Basic types of aprons include: Plastic - generally effective for oils, acids, solvents, and salts (Caution – plastic aprons have a tendency to accumulate static electricity and should not be used around flammable solvents, explosives, or materials that can be ignited by static discharge). Vinyl - best for dilute solutions of chemicals Rubber - usually heavier, but protect against acids, solvents, alkalis, oils, and caustics. 3.4 Eye Wash Station 3.4.1 The locations of eyewash stations must be identified with appropriate signage. Eyewash stations shall deliver aerated, running water for up to 15 minutes and able to be operated without hands. 3.4.3 Eyewash stations shall be located in strategic locations throughout the lab (general rule is accessibility within 10 seconds or 75 feet /30 steps from any location in the room). 3.4.4 Eyewash stations shall be flushed and checked weekly for proper operation. 3.4.5 Employees must be trained to use the eyewash properly. Training must include instruction in holding the eyelids open and rolling the eyeballs so water will flow over the eyeball and under the eyelid. 3.5 Drench Shower 3.5.1 Working drench showers shall be located in strategic locations (10 sec or 75 ft/30 steps).
